How do religions die? Generally they don't, which probably explains why there's so little literature on the subject. Zoroastrianism, for instance, lost many of its sacred texts when Alexander sacked Persepolis in 330 B.C., and most Zoroastrians converted to Islam over 1,000 years ago. Yet today old Zoroaster still counts as many as 210,000 followers, including 11,000 in the U.S. Christopher Hitchens might say you can't kill what wasn't there to begin with.

As with religion, its claims are often non-falsifiable, hence the convenience of the term "climate change" when thermometers don't oblige the expected trend lines. As with religion, it is harsh toward skeptics, heretics and other "deniers." And as with religion, it is susceptible to the earthly temptations of money, power, politics, arrogance and deceit.
